Overview
This article explains how to configure Image Upload Settings in ExSign Cloud using Amazon Web Services (Amazon S3) for storing uploaded images.

- Log in to the ExSign Portal.
- Navigate to:
System → Image Upload Settings → Cloud (Amazon S3). - Enter the following details:

- Enter a username (e.g., s3-user).
- Click Next.
4. Attach Permissions
You can either:
- Attach an existing policy directly (recommended for testing):
- Select AmazonS3FullAccess (provides full S3 access).
⚠️ For production environments, it is recommended to assign limited permissions instead of full access.
5. Finish Creating the User
6. Generate Access Key & Secret Key
- Click on the newly created username.
- Go to the Security credentials tab.
- Scroll to Access keys → Create access key.
- Choose Application running outside AWS (SDK/API).

⚠️ Save the Secret Access Key securely. It will not be shown again.

Your Amazon S3 bucket is now ready for image storage with ExSign Cloud.
